The Battle of Bard Mountain

Noxian troops tried to capture the Bard Mountains and obtain a Celestial artifact bestowed to the Ionians of the Floating villages. During the battle, the village sage was tasked to take the artifact to one of the Celestial shrine on the top of one of the villages peaks. The Noxians mortally wounded him with arrows before he could reach the shrine. However, as his last act of defiance, he used the artifact to strike his would-be-killer, obliterating him and slicing a nearby mountain in half (seemingly faltering in his duties). This misuse of the eggs power had drawn the attention of a Celestial, who promptly intervened in the event. He retrieved the artifact and took it away from the mortal plane before the Noxians and Ionians could use its power for war.
